factor x^3-4x^2-2x+20

factor

x^{3} - 4 x^{2} - 2 x + 20

(x + 2) (x^{2} - 6 x + 10)

Solution steps

x^{3} - 4 x^{2} - 2 x + 20

Use the rational root theorem

= (x + 2) \frac{x ^{3} - 4 x ^{2} - 2 x + 20}{x + 2}

\frac{x ^{3} - 4 x ^{2} - 2 x + 20}{x + 2} = x^{2} - 6 x + 10

= (x + 2) (x^{2} - 6 x + 10)

(7 - i^{2}) (2 + i^{4})

- \frac{x ^{2}}{2} + 4 x - 16

(3 x^{2}) (- 1 y^{2})

8 \times 14

(x^{2}) (5 x - 2)
